Add-ons enable you to address specific requirements by providing additional features and integrations beyond the base installation. Key features include:
● The ability to run scripts in the same manner as other tools, with generated output plan files and reports available for review.
● Invocation of Python executable scripts that can modify network models. These scripts are executed as asynchronous jobs, with results viewable within the Cisco Crosswork Planning Design interface.
For more information on configuring add-ons, see the
“Manage Add-ons” chapter in the “Cisco Crosswork Planning Design 7.2.x User Guide”.
|
| Support for importing .db plan files |
You can now import plan files with a .db extension into user space. |
|
| Topology view enhancements |
●
Utilization color profiles: Crosswork Planning now allows you to edit link colors for different traffic utilization ranges. You can now define multiple link utilization coloring threshold profiles. For more information, see the
“Utilization color profiles” section in the “Cisco Crosswork Planning Design 7.2.x User Guide”.
●
Enhanced topology plot visualization: You now have the option to bring the selected objects to the foreground in the topology plot, making it easier to view while de-emphasizing other objects. Additionally, you now have the option to completely hide unselected items for a clearer and more focused visualization.
|
|
| Network Design page enhancements |
●
Filter to selection: This feature enables you to display only the selected objects within the network summary tables.
●
Bulk action enhancements: You can now select multiple objects simultaneously and apply a range of actions to all selected items at once. You can perform actions such as Edit, Delete, Fail, and Recover, with no limit on the number of entities selected.
●
Cross table filters: Multiple cross table filters have been added in Cisco Crosswork Planning 7.2.0. For a complete list of cross table filters supported in Cisco Crosswork Planning, see the
“Cross Table Filters” appendix in the “Cisco Crosswork Planning Design 7.2.x User Guide”.
●
User-defined columns: Cisco Crosswork Planning now allows you to add custom columns to standard plan tables. Each user-defined column provides an efficient way to group columns under a single identifier and prevents conflicts with existing plan table names or columns.
For more information, see the
“User-defined columns” section in the “Cisco Crosswork Planning Design 7.2.x User Guide”.
●
Traffic display standardization: Traffic, Capacity, and Bandwidth units are now consistently displayed as (Mbps) in table header tooltips across all relevant network summary tables for improved clarity.
|
|
| Cisco Crosswork Planning Collector component enhancements |
●
Startup script support: You can now configure an external script as a first step in the collection configuration chain instead of the existing mandatory IGP/SRPCE collectors.
For more information, see the
“Run an external script as a startup script” section in the “Cisco Crosswork Planning 7.2.x Collection Setup and Administration” document.
●
Dynamic data file access at external script: You can now upload data files directly to the Cisco Crosswork Planning Collector. External scripts can access these files at run time, without requiring script repackaging or redeployment. This enables scripts in the Cisco Crosswork Planning Collector to use up-to-date, user-uploaded files during execution, supporting more efficient customization.
●
Node filter enhancement: You can now upload a CSV file in the node filter configuration with the list of nodes to be filtered.
●
Enable password support: Cisco Crosswork Planning now includes the
Enable password field on the device authentication credentials configuration page.
●
Download collector logs and record files: You can now download the logs and record files specific for a collector. For more information, see the
“Download data, logs, and record files” section in the “Cisco Crosswork Planning 7.2.x Collection Setup and Administration” document.
|
|
| Access to plan table schema |
All aspects of a plan file are defined using a collection of tables. You can now access all the plan tables from the Schema Definition page in the Cisco Crosswork Planning UI. For more information, see the “Plan tables” section in the “Cisco Crosswork Planning Design 7.2.x User Guide”. |
|
| Dark mode support |
Cisco Crosswork Planning now offers a dark theme option alongside the default light theme. The dark mode is designed to reduce eye strain and enhance comfort in low-light environments by minimizing glare and blue light exposure. Additionally, dark mode may help conserve battery life on compatible devices. For more information, see the “Enable dark mode” section in the “Cisco Crosswork Planning Design 7.2.x User Guide”. |
|
| In-product listening for Customer Satisfaction (CSAT) surveys |
Cisco products now feature integrated CSAT survey functionality. This allows users to provide immediate feedback via short surveys presented directly within the product interface. All input is delivered straight to Cisco teams, which helps accelerate improvements and streamlines the feedback process compared to previous methods like email and web surveys. |
|
| Ease of setup |
AWS EC2 support |
You can now deploy Cisco Crosswork Planning on the AWS EC2 platform. For information on deploying Cisco Crosswork Planning on AWS EC2, see the “Installing Cisco Crosswork Planning on Amazon EC2” section in the “Cisco Crosswork Planning 7.2.x Installation Guide”. |
| Software reliability |
ASLA delay and ASLA TE metrics |
Cisco Crosswork Planning now supports Application-Specific Link Attribute (ASLA) delay and ASLA TE metrics in the FlexAlgo calculation. For more information, see the “Application-Specific Link Attribute (ASLA)” section in the “Cisco Crosswork Planning Design 7.2.x User Guide”. |
| Asymmetric delay support |
Each interface in a circuit can now have its own delay metric instead of there being a single delay value for the circuit as a whole. |
|
| Representative plan file creation |
Cisco Crosswork Planning now includes the Create representative plan tool which allows you to generate a representative plan file. Representative plan files are network plans that better reflects the overall network state by combining multiple snapshots from an archive. Each representative plan includes multiple traffic levels, each corresponding to a specific time interval, offering a more accurate basis for long-term design and planning. This approach is particularly valuable for analyzing networks where peak utilization occurs at varying times across different interfaces. The topology is derived from a chosen base plan, and you can specify the desired time intervals for traffic levels, such as hourly segments. For more information, see the “Representative plan files” section in the “Cisco Crosswork Planning 7.2.x Collection Setup and Administration” document. |
|
| Global traffic level and QoS selection |
You can now create and manage several traffic levels that are globally available for each opened plan file. The selected traffic level determines the information displayed in the topology graph and network summary table calculations. Additionally, you can select QoS settings globally for each opened plan file. You can configure service classes, interface queues, and undifferentiated traffic, as well as add or edit service classes, assign service classes to queues, and add or edit service policies. For more information on how to apply QoS settings globally for an opened plan file, see the “Apply QoS settings globally” section in the “Cisco Crosswork Planning Design 7.2.x User Guide”. |
